Regulators Extended the AP1000 Through 2066. Now a Developer Wants Up to 6 in Kentucky. One Stock Owns 49% of Westinghouse.
Cameco (CCJ) owns 49% of Westinghouse, a nuclear power service provider. The U.S. Nuclear Regulatory Commission extended the license for Westinghouse's AP1000 reactor through 2066, following successful operation at Southern Company's (SO) Vogtle plants. The Nuclear Company plans to use up to six AP1000 reactors in Kentucky, potentially boosting Westinghouse's growth and Cameco's stake.
